A cylindrical platen 8 is pivotally mounted in the side bars Tand is adapt-' ed to be" line spaced by any suitable construction of line spacing mechanism.

Lugs 9 (Fig. l) project forwardly from the bottomof the shde bar (ti and secured to these lugsby screws 10 are arms -11 which extend forwardly under the platen and have pivoted to their front ends at 12 a platen scale plate 13, the upper edge of said platen scale plate being pressed constantly towards the platen by springs 14 secured on the arms. The scale plate is preferablyprovided with a suitable platen scale. .Pairsiof lugs 15 and 16 project forwardly from the slide bar 6 one pair at each side of the bar. Secured in each pair of lu s are short pivot rods 17 and ls'one above the other. Journaled on each of the upper rods 17 is a hanger arm 19, said hanger arms extending downwardly and forwardly from their pivots 17 and having journaled' in them at their lower ends rollers '20, the pivots ofv said rollers being indicated by. the numeral 21. Above the pivots 21 each han'ger arm 19 is enlarged as indicated at '22, the enlar ed portions 22 being perde journals for the ends of a shaft 23 which carries one or more feed rollers 2-l.' Flat springs 25 are secured by screws 26 to-the backs'of; the hanger arms 1!), said fiat springs extending upwardly and rearwardly from said screws and cooperating with pins 27 fixed between the lugs 15 and 16. T he springs 25 tend constantly to press the hanger arms 19 upwardly about their pivots l7 and to maintain the feed rollers '24 in (-oiipemtive engagement with the platen 8. .lournaled on the pivot rods 18 are hanger arms 28, said hanger arms oxtcnding downwardly and forwardly beneath the platen and having journaled in their free ends a feed roll shaft 291m which isnnounted one or more feed rollers 30 which are par- 'allel with the feed roller or rollers"2-l. Se-

cured by screws 31 to the under side of the hangcrarnls .28 are fiat springs 32, said springs extending upwardly and rearwardly and cooperating at their free ends with brackets 33 secured by screws 34 to the slide bar 6. The flat springsl 32 have bonds or p'ro ect1ons32 which bear against the hanger arms 25' and the springs tend constantly to the free ends of said springs 44 contacting with the under surface of the paper apron tends from side to side 0 press the feed rollers 30 upward into cooperative engagement with the platen 8. The tension of each spring 32 may be regulated by screwing in or out its associate screw. 31.

ed screws 36 which cooperate with a bracket or support 37 which pivotally supports at. 38

a paper table 39, said pa er table extending @pwardly and rearwardly from its pivots and being normally spring pressed towards the rear by a coiled spring 40. 'Forwardly of the screws 36 the lugs 35 are perforated to provide journals for a feed roll release shaft 41, said shaft extending longitudinally of the platen at its rear and the ends of said shaft being 'ournaled in the side bars 7 of the platen rame. A. paper apron 42 exthe machine beneath and at the rearof the platen, said paper apron being provided with end portions 43 which are coiled or hooked around the shaft 41, thereby pivotally connecting the paper apron with said shaft. Flat springs 4-4 are secured byscrews 45 to the upper faces of the secondary hanger arms 28,

and tending to maintain the latter in cooperative relation with the platen. The paper apron is provided with o enings 46 and 47 through which the main eed rollers 24 and- I the secondary feed rollers 30 respectively protrude to coiiperate with the platen. The

parts hereinbefore, referred to are not claimed per se herein.

Referring now to the novel releasing devices which I-pr'efer to employ in combination with the paper feeding mechanism above described, collars'48 are fixed to the feed roll release shaft 41, one collar being disposed near either end of said shaft be tween a paper apronend portion 43 and one of the lugs 35. Any referred means may be employed for securing the collars 48 in place. In the drawings I have shown a pin 49 as driven through each collar andthrough the shaft 41, thereby fixing the relation between said shaft and said collar. Each collar is provided with an ear or lug 50 ex f tending normally rearwardly from its asso i The rear -face'50 of each lug 50 is flat and serves as a locking face in a manner hereinafter described. On each collar 48 and extending oppositely from .the Lug 50isa some- .What. longer ear or lug 51, the bottom of which normally .contacts with the'beveled face 52 of'a pin 53 which is fixed on. the associate hanger arm 19 and extends upwardly therefrom. The under portion of each col- 'lar below the ears 50 and 51 is cutaway as indicated at 54 in order not to interfere with the hanger arm 19 or the pm 53 thereon.

The left end of the release shaft 41 projects laterally beyond the left hand side plate 7' of the platen frame and has secured to it by a screw 55 a crank arm or feed roll release lever 56, said release lever being provided at its freeend with a finger piece 57. Pins 58 and-59 projec laterally outward from the face of the left hand side plate 7 in position to cooperate with and limit the movement of the release lever 56.

The operation of the mechanism above described may be briefly explained. The normal positions of the various parts are shown in Fig. 1 in which it will be noted that the main feed rollers 24, the secondary feed rollers 30 and the paper apron 42 are in operative contact with the platen. The paper or work sheet is entered iirthe machine over the paper table 39 and the paper apron 42, and passes between said paper apron 42 and the main and secondary feed rollers, being fed through the machine in a known manner as the platen is turned by suitable line spacing or platen turning mechanism. hen it is desired to momentarily release or free the paper from the control of the paper feed rollers the latter may be released or moved out of operative relation with the platen by pulling the release lever 56 forwardly until it contacts with the limiting pin 59. The forward movement of the release lever 56 rotates the shaft 41 forwardly and causes the-lugs 51, acting through the'pins 53, to

press the main hanger arms 19 downwardly about their pivots 17, thereby moving the main feed rollers 24 away from the platen. As the hanger arms 19 are swung downwardly, the rollers 20 at the ends of said hanger arms, engaging the secondary hanger arms 28, will force the latter arms downwardly about their pivots 18 and against the pressure of the springs 32, said hanger arms 22 in their downward swing carrying with them the secondary feed rollers 30. The downward movement of the hanger arms 28 releases the paper apron from the pressure of the springs 44 carried by said hanger arms 28, and. allows the paper apron to drop out of operative engagement with the platen. The arts will now be in the positions shownin Fig. 2, in which it will be noted that both the main and secondary feed rollers. are in released positions havin been brought to such positions by a sing e actuation of the This leaves one hand of the operator free for adjusting the papeand as soon as the desired operation is performed the release lever-56 may be freed from pressure and the parts will be restored to their norn'ial positions under'the influence of the restoring springs 32 and When it is desired that both hands may be free' for adjustingpthe paper in the machine the feed :roll release lever 56 is pressed or swung rearwardly or in the opposite direction from that above de scribed mama contacts with the limiting pin or stop 58. As the lever is swung rearwardly the lugs 50011 the release shaft 41 will be brought into contact with the. main hanger arms 19 and will'swing the latter downwardly causing, them to more the main feed rollers 24 to releasing o; inoperative position. v v i l As before described, the rollers 20 on the. main hanger arms will act on the secondary hanger arms 28 to cause the release of the secondary feed rollers 30 and other paper feeding and guiding devices. The parts are so proportioned that when the release lever 56 contacts with the limiting stop 58 the flat locking face 50 of each lug 50 will have been turned so that it is inengag'ement with the upper face of the associate hanger arm- 19. The parts will now be in the position shown in Fig. 3 and it will be readily under-- stood from an inspection of said figure that the engagement of the two flat surfaces,that 18, of the upper surface (if-each hanger arm 19 with its associate flat locking face50" such that the parts will be maintained inthe position. shown after the hand 'of the operator is removed from the feed roll release lever 56. Consequently 'both hands of the operator are free to adjust the paper to desired position, to remove said paper, etc. Afterthe desired 'o eration has been performed the main an secondary feed rollers 1 and other paper feeding and guiding devices may be unlocked by' pulling forwardly on the release lever 56and the parts will be restored to normal position under the influence of the restoring springs.

It will be observed; that I provide. means operative whenpressed in one direction'to.
